Sun Has Many Campfires that Are Micro and Nano Solar Flares | NextBigFuture.com

The Solar Orbiter flew within 48 million miles of the Sun and took the closest pictures of the Sun to date. Other spacecraft have been closer, but none have carried Sun-facing imagers. Solar Orbiter carries six imaging instruments, each of which studies a different aspect of the Sun. Normally, the first images from a spacecraft confirm the instruments are working; scientists don’t expect new discoveries from them. But the Extreme Ultraviolet Imager, or EUI, on Solar Orbiter returned data hinting at solar features never observed in such detail.
